13) Note the altitude constraints associated with each of the approach waypoints as seen in Figure 5-126. These altitudes are loaded from the database and are displayed as light blue text, indicating these values are “designated” for use in computing vertical deviation guidance.
Note: To no longer use the displayed altitude for calculating vertical deviation guidance, perform the following:
a) Press the FMS Knob to activate the cursor.
b) Turn the small FMS Knob to highlight the desired altitude.
c) Press the CLR Key.
d) Press the FMS Knob to deactivate the cursor.
After making the altitude “non-designated”, it is displayed as white text.
Altitude constraint values associated with the Final Approach Fix (FAF) and waypoints beyond the FAF cannot be designated for vertical guidance. These altitude values are always displayed as white text, as in Figure 5-126. Vertical guidance from the FAF and on to the Missed Approach Point (MAP) is given using the WAAS GPS altitude source, therefore, the displayed altitude values are for reference only.

14) As the aircraft approaches OPSHN, it may be desirable to adjust the speed, or steepness of the upcoming descent. The default Flight Path Angle (FPA) is -3.0 degrees and a required vertical speed is computed to maintain the -3.0 FPA. To change the vertical flight path, perform the following steps.
a) Select the VNV PROF Softkey to place the cursor in the target vertical speed field (VS TGT) as shown in Figure 5-127.
b) At this point, the descent vertical speed can be selected, or the FPA can be selected. Turn the large FMS Knob to select the desired selection field, then turn the small FMS Knob to enter the desired value.
Note the information now displayed in the ‘CURRENT VNV PROFILE’ box. Also, note the offset waypoint (orange box) and gray circle are now displayed on the map. The gray circle marks the Top of Descent (TOD). In this example, vertical guidance is provided at the TOD that results in a -3.0 degree FPA descent to an altitude of 10,000 feet upon reaching the offset waypoint.

15) As seen in Figure 5-128, the aircraft is approaching TOD. Note the target vertical speed required to reached the selected altitude. The Vertical Deviation Indicator (VDI) and the Required Vertical Speed Indicator (RVSI) are now displayed on the PFD as shown in Figure 5-129.

16) Upon reaching TOD, a descent vertical speed is established which places the VSI pointer in line with the RVSI as shown in Figure 5-130.

17) When the aircraft is one minute from the bottom of descent (BOD) it is annunciated as shown in Figure 5-131. Upon reaching the offset waypoint for OPSHN, the aircraft is at 10,000 feet.
